Field archaeologists are experts in recycling – give us a random selection of old bits of string, nails, cardboard or whatever and we’ll transform them into some terribly useful bit of kit that costs next to nothing. Or failing that, a spectacular costume for the end-of-dig fancy dress party. My personal highlight was the year I morphed into Princess Leia, accompanied by R2D2 (the dig vacuum cleaner with a few judicious additions. I had to make the noises myself).

But the most common and recognisable piece of recycling would have to be the small finds boxes. Objects come in all shapes and sizes, so there is always a scramble in field work to find the perfect container to keep that bone pin from breaking as it makes its route from registrar to photographer to illustrator. Then comes the moment when objects need to be shipped abroad, and another scramble is on to find packing materials to keep everything safe in transit.
